  • the manual valve 14 in the first embodiment includes separate bodies which are the first plug 46 having the bottom 35a pressing the check valve 8 and 9, and the second plug 47 in which the operating screw 37 is screwed, then the first and second plugs 46 and 47 are individually screwed into the first recess 21. Therefore, even if the second plug 47 rotates coincident with the operating screw 37 when the operating screw 37 is rotationally operated, the first plug 46 does not rotate. Accordingly, a pressing force (a clamping force) to secure the check valves 8 and 9 can be maintained at the most preferable value at all times. Moreover, since tightening torque for the second plug 47 does not affect the pressing force to secure the check valves 8 and 9, the second plug 47 is further firmly tightened to prevent coincident rotation. In the first embodiment, the second plug 47 can be firmly tightened by a way where the flange 51 formed in the second plug 47 is pressed to firmly contact with the outside surface 16a of the housing of the plug 3.
  • the valve body 36 In a case where the pressure of the filling gas is extremely high such as a gas tank for hydrogen, the valve body 36 is forced to press against the operating screw 37 by the gaseous pressure. The force created by the pressing causes force for rotating the operating screw 37 to increase, and tends to make coincident rotation happen.
  • the tightening force of the housing 35 causes the lid bodies 25 and 26 of the check valves 8 and 9 to elastically deform, thereby exerting a preferable sealing property with the lid bodies 25 and 26.
  • the housing 35 of the manual valve 14 is configured with the individual members which are the first plug 46 and second plug 47, and thereby the configuration is useful in preventing coincident rotation and in enhancing sealing properties.
  • torque for operably rotating the operating screw 37 is preferably set lower than the tightening torque of the housing 53 in order to prevent breakage of the check valves 8 and 9 caused by excess tightening force due to such coincident rotation or deterioration of sealing properties caused by insufficient tightening force.
  • the present invention has been applied to a hydrogen gas tank in the embodiments above, the present invention may be applied to a high pressure gas tank other than a gas tank for hydrogen, or to a structure for assembling plural articles to be assembled including a manual valve for a mounting body.
  • the present invention is realized by an assembling structure for the check valves 8 and 9 and manual valve 14 (52) disposed in the filling passage 5, but the present invention may be realized by an assembling structure for a valve device disposed in another passage.
  • a valve device secured by the manual valve may be other than a check valve.
  • the tightening force of the housing 35 (53) is configured to make the lid bodies 25 and 26 of the check valves 8 and 9 elastically deform to exert preferable sealing properties with the lid bodies 25 and 26 in the embodiments described above, a configuration is possible in which a valve device is simply secured.
  • valve body 36 is settled in the first plug 46 in the first embodiment, the first plug 46 and second plug 47 are configured so that at least part of the valve body 36 may be settled in the second plug 47.
